Title: Timing circuit for providing an output signal the duration of which remains a fixed percentage of the period of an input signal
IPC: H03K5/04
Filed: 1977-01-17
Abstract: 1533093 Ignition systems MOTOROLA Inc 17 Jan 1977 [27 Feb 1976] 01784/77 Heading F1B [Also in Division H3] A solid state ignition system has sinusoidal signals derived from an engine are applied to the comparator 84, and then to a timing circuit 86 which produces an output pulse which has a constant mark-to-space ratio as the input frequency varies. This pulse which goes high to low as the sine signals cross zero in a positive direction is applied to integrators 88, 90, and thence to a comparator 92. In operation the gate 94 is inhibited during the mark period thus preventing ignition if noise is present. The output of integrator 90 falls and eventually passes through the level at the output of 88, NOR gate 94 is then enabled and current starts to flow through the saturated amplifier 96 into the ignition coil 100 and this results in a rising voltage across sensing resistor 98 which applied to a comparator 102, and so to the NOR gate, stops the current and resets the integrator 88. The output of integrator 88 is varied in response to the engine r.p.m. to regulate the dwell time to be a fixed percentage of the total firing cycle.

Title: Improvements in or relating to apparatus for sorting cards and sheets
IPC: B65H29/24
Filed: 1955-01-24
Abstract: 764,229. Sorting statistical record cards. NOON, A. W. Jan. 24, 1955 [Feb. 1, 1954], No. 2042/55. Class 106 (1). ). A device for sorting sheets of flexible material, e.g. cards, checks, &c. having identification marks or the like adapted to be sensed by scanning means comprises a rotatably mounted drum 20, Figs. 1 and 2, two rows of openings 60, 62, Fig. 4, in the periphery of the drum communicating with two longitudinal passages 56, 58, means under control of the scanning means for selectively applying suction to the two passages as the drum rotates through a desired arc and means to cut off the suction to one passage when the openings connected thereto are open and the other openings are closed by a card. The cards to be sorted are fed by conveyer bands 22, Fig. 1, under the scanning g device 12 and towards drum 20. Cards which are not selected continue in the same line of movement and are forwarded by conveyer bands 24 to further sorting stations. Rollers 27 press the cards against the conveyer bands 22, 24 and a roller 28 presses them against the drum 20. The drum is driven by a chain 26. The scanning device 12 governs a suction control device 14 connected by a pipe 16 with the hollow shaft 18 on which the drum turns and thence to the rows of openings in the periphery of the drum. Cards which are selected by the scanning device are gripped by the drum as shown in Fig. 1 and carried thereby downwardly through an arc. Peripheral slots are formed in the drum to receive fingers 70 which strip the card from the drum and cause it to drop into a receptacle 74 having a movable bottom plate 76 which falls as the weight of selected cards increases. The hollow shaft 18 has a slot 38 near one end which extends over approximately 180 degrees of the circumference so that suction is applied during the whole of the arc during which the card is carried on the drum. A block 40 secured to the drum face has a bore 42 communicating with the slot 38 and a bore 46 in a block 44, Fig. 4. The bore 46 connects to a radial bore 48 which opens into a transverse passage 50 communicating with a pair of elongated slots 52 connected with the passages 60, 62. Leaf-springs 64, 66 attached to the walls of the slots are held apart by a pin 68 so that they normally have the position shown. When the card 10 is in such a position that it closes one row of openings 62 only, the air entering the other row 60 causes the leaf-spring 64 on that side to be pressed against the side of the slot and so close that end of the passage 50. By this means, when one row of openings is uncovered loss of suction in the other row is prevented. A sheet of rubber 80 applied to the surface of the drum improves the seal between the card and the drum.

Title: Improvements in means for increasing the output of shoe making machines
IPC: A43D119/00
Filed: 1927-01-24
Abstract: 280,068. Abel, A., and Atlas-Werke P÷hler & Co. Jan. 24, 1927. Operating clutches in shoemaking machines of the kind which perform a cycle consisting of a plurality of partial operations between which manual adjustment of the machine or work piece is necessary. The machine is driven intermittently so that instead of the operator taking an indefinite time to make the manual adjustment and then re-start the machine, the time intervals for manual adjustment between the partial operations are of definite length. A constantly running pulley 3 is connected by bevel gearing to a shaft 8 which drives a worm wheel 10, either direct or through a change speed gear. The worm wheel 10 drives a countershaft 12 on which are cams for making the various machine adjustments during the cycle and a cam determining the time intervals allowed for the manual operations. The latter cam 13 co-operates with a roll on a lever 23 connected by an adjustable link 25 with a rocking arm 22 having an inclined end 21. When the roll engages low portions of the cam 13. the end 21 engages a pin 19 on a spring plunger 17 mounted on the main cam shaft 2 and normally engaging one of a number of holes 20 in the pulley 3. The cam shaft 2 drives the pulling- over and tacking mechanism, so that when the low portions of the cam come into action, the plunger 17 is retracted and this mechanism comes to rest to allow the operator to change the position of the work-piece during the cycle, and change a finished work piece for a new one at the end of one cycle and beginning of the next. The lever 23 is connected by a pawl 28 with an indicator bearing suitable inscriptions and having an aperture 32 through which the partial operation then proceeding or next to be performed may be read. A wheel 76 in the speed gear connecting the shaft 8 with the worm-wheel 10 may be moved to a free position, when the machine may be operated in the usual manner, connecting means 84 being then connected with a treadle to operate the clutch plunger 17. The link 25 may be shortened to prevent the cam 13 interfering with this manual control. Interchangeable cams may be provided for the shaft 12, which cams may be in parts held in place by screws.

Abstract: 1,113,713. Travellers for ring-spinning. H. STEINWANDT [trading as CHR. MANN. MASOHINENFABRIK]. 16 Jan., 1967 [19 Jan., 1966], No. 2178/67. Heading DID. An ear-shaped traveller for ring-spinning has a guide for the thread at its centre formed in the surface 'which bears against the ring when the traveller is in use. In Fig. 1 (not shown) the traveller is of wire and has a central integral loop forming the guide. In Fig. 2, the traveller is e.g. of plastics material and its central part 10a is widened and formed with a groove S open towards the ring, the bottom of the groove is curved to match the path of the yarn where it changes direction. The increased width of the traveller reduces the risk of its being cut through by wear, it also reduces the tendency of the traveller to tilt since the centre of gravity is disposed where the yarn changes direction. The top and bottom of the traveller and the corresponding portions of the ring are shaped as shown in section. In Fig. 3, the traveller is similar to that of Fig. 2, but it has a convex surface to bear against a concave surface of the ring. The ring may be of the self lubricating type.

Abstract: 625,331. Rivets; hinges. AIRCRAFT MATERIALS, Ltd., -and GOULD, G. H. Jan. 24, 1947, No. 2234. [Classes 65 (ii) and 89 (i)] [Also in Group VII] Hollow rivets for use in blind-riveting and made of relatively soft material, e.g. aluminium alloy, are  fitted with an external sleeve of material such as steel to increase the shear strength of the rivet. The sleeve Fig. 1 may be a press fit on the rivet 3 and is preferably shorter than the combined thickness of the plates 13 15 when riveted. The setting mandrel 9 is weakened to break below the head 11 when not required to remain in the finished joint, but where watertight joint is needed, to break at 19, Fig. 4, when the head 17 has been formed. The rivet need not have an initial head 7, with heads being formed during setting by the means described in Specification 613,882, [Group VII]. In a modification the sleeve 23, Fig. 6, extends under the rivet head by a flange 27 and initially completely covers the rivet so that the head formed during setting is substantially covered also. In other forms the head of the mandrel engages a hard washer pressed into a recess in the end of the rivet, or the recess may contain a slot for engagement by a threaded headless mandrel..Another rivet has a sleeve with a tapered end 107, Fig. 11, to engage and expand a cap 97 that covers the upset end of the rivet. When the rivet is to form a pivot for a part 149, Fig. 16, connected to a member 151, the sleeve 133 is longer than the thickness of the part. If the rivet is to be free to turn in both parts sleeves 155, 157 arranged as shown in Fig. 18 are employed. The sleeve may be mounted in a recess in the rivet. Specifications 303,126.

Title: Process for producing liquid hydrocarbons
IPC: C07C5/02
Filed: 1928-01-24
Abstract: 284,224. Hansen, F. J. M. Jan. 24, 1927, [Convention date]. Hydrocarbons.-Liquid hydrocarbons are obtained by the action of atomic hydrogen upon hydrocarbons, dissociation of the hydrogen being started before the introduction of the hydrocarbon into the dissociation zone. In an example, hydrogen is passed through a series of sparks nr an electric arc, and impune naphthalene vapour is then led in after the dissociation has started. The treated gas is removed rapidly from the high temperature zone. The admission of napthalene may be interrupted periodically while the hydrogen alone circulates through the apparatus. The Specification as open to inspection under Sect. 91 (3) (a) includes the production of liquid hydrocarbons from atomic hydrogen and carbon, and includes a modification in which the carbon or hydrocarbon is introduced into the hydrogen as near as possible to the place where the dissociation of the hydrogen is effected. It is stated that catalysts may also be used. This subject-matter does not appear in the Specification as accepted

Abstract: 840,810. Photo-electric control arrangements. ELCONTROL Ltd. May 12, 1955 [May 13, 1954], No. 2295/57. Divided out of 14011/54. Class 40(3). A light sensitive circuit for generating pulses in accordance with changes of illumination comprises a photo-cell 10 connected between the grid of hard valve VI and a point on resistor R maintained at a suitable negative potential. The output at the anode of VI is coupled to the grid of a second hard valve V2 by means of glow discharge tube 13 and the anode output of V2 which is the pulse output may be fed to a utilization circuit such as a dekatron counter S1. When the photo-cell is dark current flows in V1, the potential across 13 is insufficient to cause it to strike and V2 is cut-off due to the negative bias applied to its grid from line 14. Illuminating the cell causes it to conduct, cutting off V1, increasing the potential across tube 13 to cause it to strike and thus cause V2 to conduct. The result is a negative going front edge to an output pulse at the anode of V2, the rear edge of the pulse occurs when the illumination falls to a value at which tube 13 ceases to conduct. Differentiation results in negative and positive going short pulses at the front and rear edges of the output pulse (as shown) and if desired one or other of these short pulses may be suppressed, as for example by diode D.
